Are Black Holes Real?

Question

How can a black hole suck in light if gravity has no effect on light since its just energy? And is there such things as a white hole?

Answer 1

According to Stephen Hawking, black holes are real and I believe that the Hubble telescope has found some way off in space. Read Hawking's books and he explains them in a very straight forward, every man can understand style.

Answer 2

A black holes is among the oddest object in space and Yes, a black holes is real but I never heard of a white holes witch may or may not exist. And yes, It a black holes is so powerful that even light it self cannot escape a black holes is much different than gravity a black holes create something called an event horizon that if anything get caught in the horizon it cannot escape a black hole traps everything it eats inside a massive sac inside that sac light that have been trapped come together and make a Oven that will burn everything that come in. And black holes don't just eat they spit out too but only on the side of it the thing it eat create a power for it so the thing it spitting out is a very powerful blast that spared out to most part of the Galaxy (did I mention that black holes exist in EVERY Galaxy) and that's what control the Galaxy growth

Answer 3

Yes, black holes are real. Light is made up of "waves" and particles not just energy. A black hole is an object so dense that the escape velocity needed to leave the singularity is greater than the speed of light. White holes are a postulate that an object repels or ejects matter.

Answer 4

Black holes are thought to form from stars or other massive objects if and when they collapse from their own gravity to form an object whose density is infinite: in other words, a singularity. During most of a star's lifetime, nuclear fusion in the core generates electromagnetic radiation, including photons, the particles of light. This radiation exerts an outward pressure that exactly balances the inward pull of gravity caused by the star's mass.

As the nuclear fuel is exhausted, the outward forces of radiation diminish, allowing the gravitation to compress the star inward. The contraction of the core causes its temperature to rise and allows remaining nuclear material to be used as fuel. The star is saved from further collapse -- but only for a while.

Eventually, all possible nuclear fuel is used up and the core collapses. How far it collapses, into what kind of object, and at what rate, is determined by the star's final mass and the remaining outward pressure that the burnt-up nuclear residue (largely iron) can muster. If the star is sufficiently massive or compressible, it may collapse to a black hole. If it is less massive or made of stiffer material, its fate is different: it may become a white dwarf or a neutron star.

Answer 5

Black holes are 'real' insofar as we can observe things which behave like a theoretical black hole should behave. There is no such thing as a white hole as far as I know.

Light is affected by gravity, especially by very large gravitational objects such as black holes.

There is a really good article on black holes at Wikipedia, the free, online encyclopedia:

Hope this helps!

Answer 6

Well...Black holes are theories given by astronomers.Black holes can only be detected by a x-ray telescope in space and is invisible to the naked eye. It is formed when a star dies. A star dies after a long period of time and if it is a big star, it will expand greatly and explode, forming a black hole, then it becomes a white dwarf which is very dense.

Answer 7

Black holes don't suck in light. They warp space (and time) in such a manner that the light follows space and is essentially turned back on itself. Light will follow the curvature of space.

Answer 8

Yes, black holes are real. We can't observe them directly, but the Chandra X-ray telescope takes many images of them by observing the gas falling into a black hole, which radiates in the x-ray part of the spectrum - extrememly hot gas.

They don't 'suck' in light, but actually bend the space around them due to their immense gravitational fields (see 'general relativity'), redirecting the light. As space is bent, so light follows.

Answer 9

Yes they are real and no we cannot go through them alive. Approaching a black hole too closely would lead to your disintegration. We cannot go back into the past nor forward into the future. A black hole is a gravity well or vortex that pulls recyclable material and energy into inner-dimensional space to be recycled back into the universe itself. Black holes eat or consume energy. Before anything goes into a black hole its event horizon disintegrates it into its most basic particles and it is then swallowed by the black hole as energy.

Answer 10

No, black holes do not and can not exist.
A lot of scientists believe they do but there are a lot of compelling logical arguments against them.
